Specification of Letters Patent. Patented Atag.. 31, 19715,

Application inea Apriii,1915. serial No. 18,448,

T all whom it may concern;

Be it known that I, JOHN WALTER GRANT- LAND, a citizen of the United States, and residing at Cincinnati, in the county of Hamilton and State of Ohio, have invented a new and useful Improvement in Lubricators, of whichV the following `specification is ya full disclosure.

The invention relates to lubricators and primarily to that class known as condensation displacement sight feedV -lubricators, principally used in connection with locomotives.V In general, such type of lubricator comprises an oil, reservoir, a condenser or steam' condensing chamber located primarily at a higher elevation than the oil reservoir, a.

passage or conduit connecting the lower portion of the condenser with the lower portion of the oil reservoir, oil distributing passages either in the singular or plural number for delivering oil to distant points. p The oil distributing passages connect with the oil reservoir through regulatable feed nozzles for discharging the oil .in drops. The passages toward their lubricator discharge ends connect with the condenser through pressure equalizing tubes, and sight glasses axially located at the feed nozzle discharge end to observe the extent of oil feed. n

A feature of the invention consists providing a reservoir having its major portion approximately cylindrical with its axis extended horizontally, with the walls at its lower portion converging downward into flat surfaces'forming a contracted sub-reservoir below the normal reservoir base.y This sub-reservoir is divided `by integral transverse partitions defining, in conJunction with the'sub-reservoir walls, vertical conduits extensive -diametrically through the reservoir,

.each terminating with horizontal exit.

These oil feed conduitsare, throughout their entire length, exposed to the heated contents of the main and sub-reservoir, thereby Ving a free flow of the oil.

contracted portion of the reservoir and exrthe conduit and lenses, or yterfere with the oil feed. v

vternally. thereof, so.` that the inner yopposing lens ends-will beV approximately flush with the .relative walls of the conduits, avoiding oilpoclets, at suchfintercepting portion of obstruction to in- Other features and advantages of the in-i" i venticn will be more fully set lforth'in the description of the'kaccompanyi'ng drawing, forming a part of this specification, and in such drawings like ycharacters of reference r denote corresponding parts throughout the several views, of which Figure "l is a lcentral verticall section through a lubricator embodying my invention. Fig. 2v is a transverse vertical section on line 2-2,'F ig. l. Fig. 3 is a section on line 3 3, Fig. l. 4 is a section online 4 4, Fig. 1. Fig, 5 is a section on line 5--5,

Fig.l, illustrating onlythe reservoir.

In the lubrieators of the class providing Vfor a plurality ofindependent feeds and sight features, it has been found more practical to arrange the parts, so that they sight featuresextendin a horizontal plane, and adJacent each other, rendering it possible toy g have: all sight feed features invisible from one, or opposite sides of the lubricator. vIn

the double form it is of advantage to have the opposite observation `glasses as close toward the feed nozzle spouts as possible, without forming any obstruction in' the 'feed tube, giving a more clear sight.

The reservoir casing and glasses are sub- 4 ject at times to severe internal pressure 'and also to sudden changes in temperature, and,

therefore, structurally must be capable to withstandsuch service.r In practice, it has been found thatv the cylindrical type of reservoir casing is more practical to resist the strains.

The lubricator reservoir 1- comprises a cylindrical casing portion 2, having its axis extended horizontally. The lower portion thereof converges downwardly into Hat surfaced vertical walls 3, forming a contractedsub-reservoir 4, see Fig.[4. The endf of the cylindrical casing is provided with nipple openings. for securing suitable fittings for filling and other purposes. The sub-cellar or sub-reservoir is divided by the integral transverse partitions forming walls for the respective lvertical oil feed conduits 5, 6 and V7, which partitions together with the walls Vo f the sub-reservoir continueupwardly to extend the feed tubes diametrically through vio yboiler for supplying vsteam thereto.

the cylindrical reservoir casing, each branching horizontally into extended discharge conduits 8 to whichy the different vconnections leading to the various parts to be lubricated are connected. These horizontal branches 8 `interiorly are provided with reducing plugs 9. A ldome-shaped condenser 10 is fitted to the upper portions of thel cylindrical casing izing tubes 11 vertically extended therein,

connecting respectively-at the vupper portion ofthe cylindrical casing with branch conduits 12 cast integral with l'the casing leading to respective oil `feed'tubes or conduits to equalize the pressure within the oil feed tubes. A valve-controlled by-'pass 13 is formed within the'reservoir casing, see Fig. 2, communicating with the lower portion or base of the condenser andthrough a tube 14 with the lower portion, or'toward the normal base of the reservoir 1, providing a passage for ythe steam ycondensation from the condenser 4'intothe reservoir to displace the oil. l" l Y 15 represents an oil supply conduit extended vertically 'through-l the sub-reservoir and reservoir, and communicating with the upper portion of the reservoir, andy connecting with a horizontal "supply conduit or.

chamber 16 at the base of the sub-reservoir,

see Fig. 1. This oil supply'chamber 16 ccnnects through branch conduits or ports with the various oilfeed conduits 5, 6 and 7 of the series, and the control to each may be independent' or in series to meet the various requirements. At 'the base of each oil feed tube, a feed nozzle 17 is provided and projected upwardly into thejoil feed conduits and the supply to each controlled by a valve 18, secured to the base of the sub-reservoir. This disposes Vall of the feed regulating valves in an adjacent position freely accessible from either side of the lubricator. Adjacent the discharge end of each of said drop feed nozzles 1T respectively, I provide oppositely disposed observation glasses 19, '19, see Fig. 2, which intercept the walls of the conduits, each projecting into an aperture therewith to present the ends of the glasses substantially flush with the interior surfaces of the conduits. These glasses are socketed within' the nipple extensions 20,

formed integral with the sub-reservoir walls and projecting externally thereof and screw threaded to receive a follower plug 21 for securely mounting the 'glasses in position.

'Ihe lubricator is provided with the usual drain ports and plugs or auxiliary feed out- Y lets to meet the various requirements in their use. e

The vconstruction of feed nozzles, fsight glasses, valves, etc., may be of any wellknown construction, as they do not enter as a Vfactor to the features of the invention herein, and thus the different elements may "be variously modified within the province of thisinvention. rIhe operation is not changed and as this is well known in the art, it is deemed v not necessary to dwell thereon,

`Vith my improved reservoir and integrally combined-oil feed conduit structure, the efficiency of the lubricator is materially increased in that the oil has no opportunity to cool in its passagev through the conduits, for eachy of the conduits andthe various supplyv branches alll have surfaces exposed to the heated water or oil lin the reservoir or sub-reservoir, thus'at allltimes maintaining the oil in a condition to flow freely. The feed conduits as arranged form a straight passage of an enlarged area in cross-section with no obstruction to interfere with the vertical trendof the oil drops,

' assuring regularity of feed irrespective of scribed, a reservoir having its upper portion enlarged and extending Iaxially horizontally, the reservoir walls downwardly converging and being projected below said enlarged portion, Vproviding a reservoir -extension of reduced area below the maj or reservoir, there being integral transverse partitions in said extension, defining in conjunction with the walls of said extension, a series of oil feed conduits-within thefreservoir base, said conduits being integrally extended upwardly and centrally through the major portion of the yreservoir to a series lof horizontal outlets, one for each of the vertical conduits, an equalizing steam conduitl for each horizontal outlet, a 'horizontal oill supply conduit in the base communicating with the lower portions of said oil feed conduits and receiving oil from the major por-V tion of the reservoir, drop feed devices inA the base of said oil feed conduits, the wallsofthe reservoir base delining the lower portion of the oil feed conduits being apertured, and sight-feed features supported on the exteriorv walls of said reservoir extension adjacent said apertures, the lower portions ofthe oil feed conduits defined by said partitions being in direct contact with the hot water Vcondensation inl said reduced reservoir extension.

2. In a condensation displacement lubricator, an oil reservoir casing having a cylindrical major portion, with its axis substantially in a horizontal plane, its walls at its lower portion converging downwardly into a contracted sub-reservoir, transverse partitions dividing said sub-reservoir casing, and

With the casing Walls providing conduits continuing therefrom centrally through said cylindrical reservoir casing.

3. In a condensation displacement lubricator, an oil reservoir casing having a cylindrical major portion, with its axis substantially in a horizontal plane, its Walls at its lower portion converging downwardly into a contracted sub-reservoir7 transverse partitions dividing said sub-reservoir casing, and With the casing Walls providing conduits continuing therefrom centrally through said cylindrical reservoir casing, and observation glasses having a horizontal axis supported upon opposite sides of said sub-reservoir casing, and external of the reservoir.

In Witness whereof, I hereunto subscribe my name, as attested by the twosubscribing Witnesses.
